Every murderer is probably somebody's old friend.

I have wanted . . . to commit a murder myself. I recognized this as the desire of the artist to express himself! . . . But-incongruous as it may seem to some-I was restrained and hampered by my innate sense of justice. The innocent must not suffer.

Heather Badcock meant no harm. She never did mean harm, but there is no doubt that people like Heather Badcock (and like my old friend Alison Wilde), are capable of doing a lot of harm because they lack - not kindness, they have kindness - but any real consideration for the way their actions may affect other people. She though always of what an action meant to her, never sparing a thought to what it might mean to somebody else.

There is something about conscious tact that is very irritating.

When you find that people are not telling you the truth---look out!

too much safety is abhorrent to the nature of a human being.

There is no greater mistake in life than seeing things or hearing them at the wrong time.
